This invention relates to a safetydevice for clothes wringers and thelike and relates particularly to a feeding means therefor wherebyarticles of clothing can be passed through the wringer without danger tothe operator andwithout any necessity for the. operator bringing hishands into contact Swith the rolls. The invention has for one of itsprincipal objects to provide a. feeding mechanism of simple.construction which can be conveniently operated and which may be easilyapplied to power driven wringers of the kind now commonly employed inconnection with domestic washing machines and elsewhere.

1 The invention has for a further object to provide a feeding devicehaving a movable feed plate wherein the feed plate is housed when ininoperative position'so that it will not become engaged with the clothesbeing drawn into the rolls and it Will-not tear the clothes as they aredrawn in through the rolls. i

A further important object of the invention is to provide adevice ofthis kind wherein the feed plate is resiliently supported along itsfeeding edge so that it will function to yieldably hold the clothesagainst the upperroll over which it is drawn into the pass between the.rolls and which can yield to. the thickness of the material being passedthrough the wringer.

The nature of the invention may be readi- 1y understood by reference tothe accompanying drawing which illustrates a preferredembodiment of myinvention and; in which:

Figure 1 is a front elevation of a wringer frame and rolls of commonconstruction showing my invention applied thereto, part of the structureofthe'feeding device being broken away to show-the operating parts.

Figure 2 is a transverse vertical section in the plane of line ofFigurel.

Figure 3 is a horizontal section in the plane of line 9-3] of- Figure 2.

Figure' l is'an enlarged section also. taken in the plane of line new ofFigure lshowingthepart-s'in greater detail and showing the feed plate ininoperative position.

Figure 5 is a view similar to Figure 4 showing the feed plate inoperative position.

Referring more particularly to the draw- -ings, .7 designates theupright frame members of a wringer, 8 are the cross pieceseondesignated. 11.

necting theuprights, 9 and 10are the usual upper. and lowerrpllsrespectively, and these are arranged to be driven. from one end inany well known manner. The usual guard plates provided at each end ofthe rolls are My invention comprises astructure adapted to be secureddirectlyuto the wringer frame, and has a pair of. side plates 12 whichare. secured to the respective uprights 7. In each of, the side plates12isa diagonally disposed. slot 13, this slot extending up- .wardly andinwardly, as best shown in Figures 4 and 5. Received lwithin the slots13 of the respective platcs 12 are the opposite [ends of-a guide bar 141which extends across rthedistance between the two plates 12. Ex-

tending across between the two side plates IZt-here is also a, feedplate 16 having keepers oryokes 15 secured, tothe inner face thereof.The cross bar 14' passes through thekeepers or yokes 15 so that theplate is loosely connected" with the cross bar.

The lower edge of: the feed plate 16 is loosely turned over the edge ofa cross bar 17, which cross bar has arms 17 at. each side thereof.Thearms 17 a are outwardly curved at their-inner ends and pass throughbearings 18 in the side plates 19, which are located immediately outsidethe plates 12, and are forwardly bent outside the plates 19 to provideoperating handles 20. lVhen the operating handles 20 are raised from theposltionfs'hown in Figure 1 tothe position shown in Figure 5fthe feedplate 16 is rocked through a corresponding are, and the plate is guidedin its movement through this are by the cross bar 1.4. By reason of thekeepers or yokes 1.5 beingrelatively large with respect to. the crossbar14, the plate 16 has considerable freedom of movement, transversely,relative to. the cross bar 14. In order to resiliently urge the plate 16outwardly away from the bar 14 leaf springs 22. are provided on the barand the outer ends of'these springs bear against theinner face of'theplate was shown, thereby tending to urge the uppermost or forwardmostedge of the plate 16 outwardly. When the plate is rocked as hereinbeforeexplained from the positionshown in Figure 4 to the position shown inFigure 5, the forwardmost edge, of the plate can yield downwardly whenit comes in contact with the upper roll. If clothes are being fedthrough the Wing er, the edge of; the plate 16 may be depressed an'amount' equal to the thickness of the clothes so that the clothes willbe resiliently. held against the lower surface of the upper roll anddrawn by the movementof this roll where near the pass between the rollsand into the pass between the two rolls. p

One or more springs 24 may be secured about the laterally turnedportions of the arms 17*, with one end ofthe sprin hooked, to the arm 17and the other en of the spring hooked into the plate12 for:res1lientlyurging .the feed plate. from the extendeclor operative positionas shownin F igure. 5 to the retracted or'inoperative position of Figure =4; a

Secured to the supporting side plates 19- is a curvedverticallyextending guard plate 25, and the curvature of thisuplateconformssubstantially to the curvature! of .thez-feed plate 16. 1When thefeedplate is in its inoperative or retracted position it lies within theplate 25 and closely adjacent thereto, as clearly. shown in Figure 4..The w1dth .of

the. plate 25 is only slightly greater than the width of the plate 16.The plate 25 encloses all of the operating parts of thefeeder. andprevents clothes which-- are being drawn through? the WIlIlg81- frombearing. against the plate '16 and prevents the .clothes from being.torn by being pull-edinto contact with any. of the operating parts ofthe feeder mechanism. The -mechan ism is-further guarded. and enclosedby housing plate 27 having a vertical portion and-a horizontal upperroll. I

contact with the lower surface of the upper roll are drawn into the passbetween the portion, the formerportion forminga back wall for the feederand the latter-forming a bottom closure plate for the feeder. =Guards 23may be extended forwardly-from eachof the side edges of theplate 25.Thesesguards 23 have a downwardly-turned flange portion attheir loweredge adapted to engage with shoulders on opposite side edges ,of theplate 16 to limit the forward movement of the *plate lfi'so thatunderno. conditions can the plate be drawn into the-rolls.

- Vhen the feed .plate is in the retracted position shown in Figure 4there is a pocket or trough 26 formedby the several parts and into thistrough the ends of the clothes to be wrung are placed. The handles 20are then raised, and the forwardmostedge of the feed plate 16*carries'theends of the clothes so positionedagainst the lowersurface ofthe The clothes thus. brought into rolls. WVh'ere -the clothes are notbunched, or where the'material is relatively-thin the plates 16 willyieldonly slightly, but where the clothes are thick or are considerablybunehed,-.the plate 16. can be pressed downwardly against the. pressureexerted by springs 22 to an extent sufficient to-permit I 1 Thefeeden'asherein described issimple to operate. Inasmuch as it isonlynecessarythat the ends of the clothes be laid over top of the guardplate25 there is no necessity for the operator to bring his fingersanyoperation ofv wringing can be quickly per- .formedso thatnoadd-itional time is consumedinusing a deviceof this kind.

- In the'accompanying drawings and description I. have illustrated anddescribed a preferred embodiment of my invention but it will-beunderstood that the invention may .be otherwise embodied and thatvarious changes andmodilications' may be made in the structure thereof.within the contemplation of my invention and under the scope of thefollowing-clain'is.-
